Nebula Blog Invitational – Mailsphere

Ever since the first emails were sent in 1971, people have stretched the limits of what email can do.

Those first emails, sent across the ARPANET network by Ray Tomlinson, contained the crucial ‘@’ character to separate the user name from what was then the machine name. That initial choice of the @ character has doomed countless corporate employees into being bombarded with instructions and information and a unique modern form of Inbox based stress.

Since that time, the death of email has been constantly predicted. Much of that prediction is wishful thinking, and people see email as the cause of their information overload, rather than what it truly is, a symptom of our connected and busy world. Slack has emerged as the darling of enterprise messaging, and yet many companies have found that it has added to the communication overload rather than solving it.

Indeed, the volume of corporate email sent is steadily increasing. A report published by Radicati shows that email will increase from 116 billion business emails per day in 2015 to nearly 140 billion by 2018 resulting in a 20% increase in just 3 years.

As a protocol, the basic SMTP format of email must rate as one of the most heavily used, one that has been taken way beyond the use cases that were envisaged for it. An email today is a carrier of documents, calendar arrangements, rich media, and above all, corporate strategy.

Indeed, email is still the only platform that can satisfy the regulatory communication needs of an enterprise.

We often hear the myth that email cannot be used on an evidentiary basis when it comes to a dispute or legal case. The law in this respect does differ slightly between the UK and USA, but the reality is that email has been the centre of many a legal action, and there are strong requirements on how a business should treat its email data.

It is unlikely that Ray Tomlinson expected any of this, or that the future of the Democratic candidate Hillary Clinton would ultimately depend on her management of an email server.

However, although email has stayed at the core of the modern enterprise, the cost of managing an email archive has not kept pace with the wider cloud industry. In a world where you can sign up to Dropbox, Google Drive, OneDrive or Amazon Cloud Drive and store a terabyte of data for almost nothing, why is enterprise email so expensive to archive and recover?


Mailsphere was created to address this issue. Founded out of the AWS Activate program and graduating from London’s SeedCloud incubator, Mailsphere leverages both the advanced technology and low cost storage of AWS to deliver email filtering and archiving as a cost effective cloud product.

Backed by founders of MessageLabs and investors from across the industry, Mailsphere provides a flexible, cloud based, secure platform to support the ever important email platform for the enterprise.
